Induction curing of encapsulates

Abstract

The effectiveness of using induction heating for curing encapsulates in the manufacture of stators and armatures is presented. This paper focuses on a comparison of using convection oven heating vs. low frequency induction heating on a typical motor stator. Key characteristics such as time, temperature, and uniformity are analyzed. Low frequency (60 Hz) induction and traditional methods of heating available for encapsulation curing are discussed. The effect of frequency selection on induced heat depth will be discussed. Energy cost per piece, work in process requirements, and overall system flexibility is compared.
